P4C1024

The P4C1024 is a 1,048,576-bit high-speed CMOS static RAM organized as 128Kx8. The CMOS memory requires no clocks or refreshing, and has equal access and cycle times. Inputs are fully TTL-compatible. The RAM P4C1024 operates from a single 5V±10% tolerance power supply.

Access times of 15 nanoseconds permit greatly enhanced system operating speeds. CMOS is utilized to reduce power consumption to a low level. The P4C1024 is a member of a family of PACE RAM™ products offering fast access times.

The P4C1024 device provides asynchronous operations with matching access and cycle times. Memory locations are specified on address pins A0 to A₁₆. Reading is accomplished by device selection (CE ₁ low and CE ₂ high) and output enabling (OE ) while write enable (WE) remains HIGH. By presenting the address under these conditions, the data of P4C1024 in the addressed memory location is presented on the data input/output pins. The input/output pins stay in the HIGH Z state when either CE ₁ or OE is HIGH or WE or CE₂ is LOW.

Package options for the P4C1024 include 32-pin 300 mil DIP and SOJ packages as well as 400 mil SOJ.
